2020-2026 Audi Whining Noise at High Speeds TSB 2079696/1

Owners of various 2020-2026 Audi models may experience a distinct Audi whining noise high speeds within the vehicle interior. This issue, described as a "whining noise in the vehicle interior at high speeds," can manifest as various sounds, including general noise, buzzing, droning, or even singing, depending on the specific conditions and the vehicle's equipment. Audi Technical Service Bulletin (TSB) 2079696/1, released for publishing on October 17, 2025, provides guidance for technicians to diagnose and address this customer complaint.

Symptoms

Customers typically report a whining noise high speeds that is noticeable within the passenger compartment. This noise is often described with terms such as:

• "noises, vibrations -> too loud" (affecting the passenger compartment, vehicle front, or vehicle rear)
• "noises, vibrations -> noise" (in the vehicle front, passenger compartment, vehicle rear, or general vehicle areas)
• "noises, vibrations -> buzzing" (in the passenger compartment, vehicle front, or vehicle rear)
• "noises, vibrations -> droning" (specifically noted in the passenger compartment)
• "noises, vibrations -> singing" (often related to the tires or tire tread)

These sounds are perceived at high speeds and can vary in intensity and character based on individual perception, vehicle equipment, and specific vehicle versions. The complaint can originate from various vehicle areas, including the entire vehicle, specific vehicle areas (front, rear, passenger compartment), or chassis components like wheels and tires.

Technical Background

The root cause of the Audi whining noise high speeds is identified as toroidal resonance. This phenomenon occurs when the air column inside a tire vibrates. When a tire starts to vibrate due to road contact, it can lead to cavity resonances within the tire itself. These resonances are then transmitted through the wheel rim and the vehicle's running gear into the interior, where they become audible.

Toroidal resonance typically produces a frequency noticeable between 180 Hz and 250 Hz, irrespective of the vehicle's speed. The specific design of the vehicle and the unique properties of different wheel and tire combinations contribute to how and why this particular whining noise occurs at high speeds.

Diagnosis and Service

To accurately diagnose the Audi whining noise high speeds and link it to TSB 2079696/1, technicians are instructed to use specialized equipment. The preferred tool for analysis is the VAS tool 611015, which is a Pico NVH (Noise, Vibration, and Harshness) tool. When using VAS tool 611015, technicians should also consult TSB 2070568, which provides a detailed measurement description and frequency analysis guidelines.

It is crucial for technicians to explain the technical background of toroidal resonance to the customer. If the observed noise falls outside the specified frequency range of 180-250 Hz, further diagnostic analyses are required to identify other potential sources of the noise.

Repair Procedure Summary

The TSB 2079696/1 outlines a detailed diagnostic procedure rather than a direct repair, as the issue is related to inherent tire and wheel characteristics. The process focuses on precise measurement and documentation:

1. Initial Setup and Noise Analysis Tool Configuration

This initial step involves setting up the noise analysis tool, specifically the VAS tool 611015. All work performed during this setup must be thoroughly documented. This includes attaching photos of the sensor positions used during the measurement, with at least one photo clearly showing the Vehicle Identification Number (VIN) to the billing TAC case. Each photo must be labeled descriptively, for example, "sensor A measurement setup 01." This operation is designated as labor operation 0161 0000 and is allotted 50 Technical Units (TU).

2. Measurement and Test Drive

Following the setup, a measurement drive is conducted to collect data related to the noise and vibrations. It is mandatory to record the vehicle's mileage both before and after the test drive. This step falls under labor operation XXXX 0199, and the billing for this will be based on the time required, with all work needing clear documentation.

3. Analysis and Evaluation of Measurements

After the test drive, the collected data is analyzed and evaluated. Technicians must document this analysis by attaching screenshots of the measurement report from the analyzed case to the billing TAC (Technical Assistance Center) case. This is also part of labor operation XXXX 0199, billed according to the time required.

4. Repositioning Measuring Technology

In some cases, it may be necessary to reposition the noise analysis tool for further measurements or analysis. If repositioning is required, the reason for doing so must be documented. Additionally, photos of the new sensor positions, with appropriate labeling (e.g., "sensor A measurement setup 02"), must be taken. This repositioning is covered under labor operation 0161 3199, with an allowance of 25 TU.

Required Tools

To perform the diagnostic procedures described in TSB 2079696/1, the following specialized tool is required:

• VAS tool 611015 (Pico NVH tool)

Important Warnings

Audi emphasizes the importance of adhering to the prescribed procedures. Technicians are advised to:

• "Please observe the information in the repair operations list on which repair operations must be carried out beforehand, which are included, and which must be carried out afterwards if necessary."

This ensures that all diagnostic and documentation steps are followed correctly, leading to an accurate assessment of the Audi whining noise high speeds.

Warranty Information

For vehicles that are no longer under warranty, this Technical Service Bulletin serves as informational guidance only. All warranty claims submitted for payment must strictly comply with the Audi Warranty Policies and Procedures Manual. Claims are subject to review and audit by Audi Warranty.

The specific Service Number for this issue is 4440, and the Damage Code is 0055. All claims should include the comment "As per TSB 2079696/1" for proper processing. The labor operations and their associated time units are detailed above, including 0161 0000 (50 TU), XXXX 0199 (time required), and 0161 3199 (25 TU).

Additional Information

All part and service references provided in this TSB (2079696/1) are subject to change and/or removal. Technicians should always check with their Parts Department and/or ETKA for the latest information and parts bulletins. It is also recommended to check the Repair Manual for fasteners, bolts, nuts, and screws that require replacement during the repair. This document is copyrighted by Audi of America, Inc. ©2025.
